Brucite occurs in a white, yellow, gray-blue, gray or blue color. It exhibits perfect cleavage, transparent appearance, non-fluorescent luminescence, and non-magnetic properties. The mineral has irregular fractures, vitreous luster and white streak. It can be formed as lamellar structures or fibrous crystals. The average density of the mineral is 2.39 g/cm3, and its hardness ranges from 2.5 to 3.
It was first described in 1824 and named for the discoverer, American mineralogist, Archibald Bruce (1777–1818). A fibrous variety of brucite is called nemalite. It occurs in fibers or laths, usually elongated along, but sometimes crystalline directions.
Use of brucite
Brucite is an industrial mineral with special value due to its high content of useful components, low content of harmful impurities, and its unique physicochemical properties, which are different from other types of magnesium-containing mineral raw materials. The main uses of brucite is as below:
1. Flame retardant additives in rubber, plastic and fiber
2. Flue gas desulfurization
3. Aluminum composite panel
4. Paper industry
5. Agriculture and fertilizer uses
6. Environmental protection field (Wastewater treatment)
7. Magnesia high temperature refractory
8. Fireproof coating
9. Neutralize the treatment agent and adjust the pH value
